f•YA~/d ~7' ~ Reclamation Plan - Burros Presently the only xaste being dumped on the surface is that belong- ing to a third party leasing minerals from ERDA and subject to reclamat in through the terms of that lease. Union Carbide is responsible for She other surface facilities used by the contractor in conjunction with removal of this mineral. In the future UCC may again be extracting mineral. and xaste, and depositing it on these properties. Current life of the mine estimates are 10-15 years, therefore very little, if any, reclamation work can be done until cessation of mining activities. The surrounding _a:ds are used as dry rangeland and wi13_ife habitat, therefore the reclamation choice is to return the "affected lands"to grazing and wildlife values. The reclamation xill be conducted in t}[ree phases. I. Clear.-up: to be completed within approximately two years after permanent cessation of mining activity. This phase will require clean-up and removal of surface structure:., extraneous debris and other removable surface facilities from the affected lands. The portal, ventholes and shafts will be sealed or closed to prevent hazards and unauthorized entries. Cement pads an3 other permanent foundations ti~ill be removed or covered with topsoil. II. Earthmoving: to be completed within two years of permanent cessation of mining activities. This phase will involve the recontouring of roads, cutbanks and dump surfaces to aE~proxi- mate existing contours and prepare a seeding surface. Dumps containing sub-economical mineral values today are ant].cipated to be of value in the future and therefore need to be ].eft in such a manner as to make them accessible as conditions may dictate. Crests of dumps will be rounded off to slope:; of 14-25 degrees with berms at the edges to entrap run-of} water, sediments and natural seeds. Sma11 berms a[.d impoundme:nts will be placed on the surface in the appropriate drainage direction to again entrap water and :sediments. Where feasible, cutbanks will be blended into dump surfaces to match natural contours. Roads xi11 be water barred at appropriate places and cutbanks will be resloped where necessary. A11 surfaces xill be scarified to break the cr~isr, and dragged. Our experience indicates that rurfaces that <ire too smoothly prepared on slopes are not effective in retaining, moisture, sediments and natural seeds. Therefore, it is bent to ].cave small gouges and ridges from cat tracks and blade:;.
